Primary harmonic eliminator inspection method
Primary harmonic eliminator volt-ampere characteristic test
Use a peak milliamp meter (or peak voltmeter) to measure the harmonic elimination The volt-ampere characteristics of the device. The test wiring method is shown in Figure 6.

Primary harmonic eliminator flow test
Use the above method to increase the current to ~~~ minutes and then heat the sample to ℃~℃, then spray with cold water There should be no damage if exposed to water.
Note that this test will produce smoke due to temperature rise at ~ minutes. This is normal and will not damage the harmonic eliminator.
Instructions for selecting a primary harmonic eliminator
The series of harmonic elimination resistors can be divided into three types according to the rated voltage of the power grid where they are located. br/> In addition to the rated voltage of the power grid, the selected model of the detuner is related to the rated voltage of the power grid. It is also related to the insulation level of the high-voltage winding tail (end). Since the harmonic eliminator is a nonlinear damping device connected in series between the neutral point of the primary winding and the ground, its nonlinear characteristics make the harmonic eliminator have a certain resistance value in the normal operating current section, thereby effectively limiting high-voltage inrush current and iron Magnetic resonance. However, when an abnormally large current occurs in the power grid (such as lightning strike, three-phase unbalance, power grid disconnection and resonance), a relatively high voltage will be generated, causing the ferromagnetic resonance to occur. If the insulation level of the tail end is not high (commonly known as weak insulation) , the tail end of the high-voltage winding is output together with the secondary side), the insulation of the tail end may be damaged. In response to this situation, the series of harmonic elimination resistors are divided into type and type due to different insulation levels of the tail ends.
